The History of Silk
Silk is one of the most famous materials in the world. It has been used for thousands of years. Silk was first made in China around 2700 BC. According to legend, the Chinese Empress Leizu discovered silk when a cocoon fell into her tea. She noticed that the cocoon was made of a long, soft thread. This thread could be used to make beautiful fabric.
